ELECTRIC IRON.

Application led Hai-ch 24, 1919. Serial No.

To all whom t may concern.'

Be it known that I, JosrzrH A. Gonna, a citizen of the United States, residing at Marion,`in the county of Grant and btate of Indiana, have invented certain new and useful Improvements in Electric Irons; and I do hereby declare the following to be a full, clear, and'exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to sad irons, and more .especially to electric irons, and aims to provide such a device comprising a novel construction and assemblage of the component elements, to enhance the efliciency of the iron, to enable it to be readily taken apart and the heating unit renewed quickly, and to provide other advantages.

One of the objects of the invention is the provision of such an iron composed of a main block or casting with which the electric heating unit is assembled in a novel manner, to efliciently heat the face of the iron, and toralso provide for the ready'removal and replacement of the resistance wire When burnt out.

A further object is the novel assemblage of the top or cover with the bodyor main part of the iron, to provide for simplicity' in construction and efficiency.

A still further object is the provision of novel means for the connection of the electrical conductors with the heating unit.

With the foregoing and other objects in view which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed without departing from the spirit of the invention.

The lnvention is illustrated' in the accompanying drawings, wherein igure 1 is a -plan view of the iron with the cover removed.

Fig. 2 is a longitudinal vertical section, portions being shown in elevation.

Fig. 3 is a cross section taken on the line 3 3 of Flg. 2.

Fig. 4 is a plan view of the body or block of the heating unit.- Y

The body or main part of theiron, which is preferably a metal castin com rises a base late 1, the lower ace o which provi es the face of the iron, and a block 2 Specification of Letters Patent.

' accommodate the upstanding from the plate l, and of smaller outline, so that the edges of said plate extend from the block 2. The block 2 is shorter t-han the plate 1 and is provided at lts forward end with a. reduced extension 3 proJecting toward the point or forward end of the plate 1. The block 2, in order t0 heating unit, is provided with a longitudinal tunnel or opening :t therethrough from end to end, and extending under the extension 3. This tunnel 4 1s relatively wide so as to extend over a relatively large portion of the plate 1, but is of small height, being immediately over the plate 1.so as to be close to the face of the 1ron. v

The heating unit of the iron embodies a plate or flat block 5 of porcelain or similar insulating material, which is slipped longitudinally' into the tunnel 1 with its ends protruding from the ends of the tumiel, and the forward end of the plate 5 has a reduced extension 6 projecting below the extension 3. This plate is therefore disposed over the plate 1 throughout the greater portion of the area thereof, excepting at the edges of the plate 1. and close to the face of the iron. This plate 5 fits snugly within Ythe tunnel. and remains in place after once being inserted. excepting for purpose of removal when broken, which is notvapt to occur. The plate 5 is provided with longitudinal bores or passages T, some of which extend through the extension 6, and a resistance wire 8 extends longitudinally back and forth through the bores 7, and is preferably coiled. This wire can be readily inserted back and forth through the plate 5, and when burnt out can be readily pulled out of the plate 5 for the insertion of a new wire, which will require but a few minutes time.

In order to connect the electrical conductors or wires with the heating unit, a binding post bracket 9 is attached to the rear end of the block 2, this bracket being formed of a sheet of insulating material, and being seated within an up er recess 10 in the block 2 near the rear en thereof and made secure by mea-ns of screws 11 or the like. The biacket 9 has an offset portion 12 at its rear end provided with depending ears 13 extending within a recess 14 in the rear end of the block 2, and said ears 13 have binding posts 15 to which the terminals of the wire 8 are clamped by the nuts on said posts. The binding posts 15 are Patented Sept. 21, 1920.v

' trically connect the usual cord or wires w1thbinding posts,

done at the outside of the bracket9, the con-y Vvdisconnected from the iron, as well known. In renewing the resistance wire 8, the terminals thereof are the binding posts 15, and when the new wire is inserted, it is only necessary to connect the, nds Athereof t9 said which can be conveniently nections on the interior of saidbracket being permanent.

The cover or top 18 of the iron, which can be of pressed sheet metal, surrounds and extends over the block 2, and has its edge extendingdownwardly'to seat on the so that the l plate edgeportion of the plate 1 around- .the block 2 thereof. VIn order to prevent displacement of the body and cover,studs 19 are set in the plate`1 at-the three corners thereof, as seen in Eig. 1, and said studs -upstand from the plate 1 and have their sides cut or iled away, as. at 20, ,to fit snugly within the ycorners of thecover 18. Therefore, when the cover is slipped down on the body, the corners thereof snugly t *the studs 19, thereby preventing the cover and body from shifting out of place. The cover is provided at the top .with a longitudinal depression 22 in which the lower portion of the handle 23 `is seated, and a clamping.

screw 24'extends downwardly through the lower portion of the handle 23 and through the depression 2v2 into a threaded socket in the block 2, thereby clamping the handle on the cover, and at the same time, clamping the cover on the body with a single securing element. The rear portion of the cover 18 has an outstanding neck 21 surrounding the fingers 17 to receive the coupling or plug that engages the fingers 17 With the present construction, the main part of the iron is integral and comprises a single casting, including the plate 1 and block 2, and the heating unit is close to the face of the iron,

heat will be efliciently transthe 5 through which the resistance wire extends, with said plate located'close to the mitted to said face. By the provislon o i unit is usually disposed,

face of the iron, ciently, without the objections resulting from the use of mica as -now used in electric irons between sheets of which the resistance and around which the resistance wire 1s usually wound which separates the same into upper and lower portions. Furthermore, the present constructionis simple, and permits of repairs being made quickly.

Having thus described the invention, what is claimed as new is 1. VAn electric iron thev iron is heated eilicomprising a base platehavingan upst-anding block of smaller outline, said block having a tunnel therethrough adjacent to said plate, a plate of insulating material extending through said tunnel and having bores extending therethrough, a resistance' wire extending back and forth through said bores and extending from each bore to the next beyond the ends of the bores and being removable from said bores, and a cover surrounding said block and plate of insulating material and seated on the base plate.

2. An electric iron embodying a metallic block having a tunnel, aninsulating plate extending within said tunnel and having bores, a resistant wire extending back and forth through said bores, an insulating bracket securedon 4said. block at one end of the tunnel and having an offset cverhanging said end of the tunnel, the corresponding end of the bloc-k having a recess, and said bracket having ears below said offset portion disposed in said'recess, binding posts extending through said ears for the connection of the terminals of said wire at the outer sides of the ears, binding posts carried by said offset portionand having upwardly. extending contact fingers at right angles with the first named binding posts, and electrical connections between the portion first named and second namedY binding posts between said ears and under said offset portion.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
